Do what the man says, switch out one of the curls and put deadlifts first on back day. I would also consider ditching the shoulder day and putting shoulder press instead of hammer incline on chest day. Pullovers are also more of a lat movement so i'd do dips instead. Make it a 3x week program.
That way you could do:
Legs (Squats, Leg Press, Leg Extension, Glute Ham Raise, Calve Raise)
Push (Dumbell Bench, Shoulder Press, Dips, Flys, Pushdowns)
Pull (Deads, Pullups, Seated Row, Single Arm Pulldowns, Curls)
This is a much more solid program, and didn't really have to alter it too much. For the most part your exercise selection was pretty good, a lot better on the whole than the last program you posted
